I need some general advice. Geth on debian OS

I need some specific advice.I don't really know what I'm doing.I've been meaning to reach out for some time, just didn't have the chance. I realize I should have figured this out by now.

I started running geth on a cluster that I was not using,CPU mining even though I didn't/don't know how it would do, just a little project.The processes crash eventually, so I would just start it again when I was home and noticed it stopped.I did this for about a month. I know.

Then a friend gave me some of his extra rpi zero boards, and I still not knowing exactly what I was doing, put a parity system on 2 of them and a geth homestead system on another.

So now there are 8 boards all together.

I've tried the 'check balance' commands but I'm incompetent.Talk to me like I'm an idiot.

I cropped details out, but here's a screenshot of the processes starting.Do I even have currency? Could I possibly have done this right actually?
